India's largest battery storage reshapes daily power reliability - Adani Group

A Groundbreaking Battery Bet at Khavda

Look, India’s power future just got a practical upgrade. At Khavda, Gujarat, the Adani Group plans to build India’s largest battery storage system, with 1,126 MW of power capacity and 3,530 MWh of energy storage. The project is slated to be completed by March 2026 and is described as one of the world’s largest single-location deployments. The ambition doesn’t stop there: the plan envisions scaling to 15 GWh by 2027 and expanding to 50 GWh within five years. The installation will use advanced lithium-ion battery technology and smart energy management to tame peak demand and shift energy use to times when renewables are plentiful.

This isn’t just a science experiment. It’s a real step toward stitching together India’s growing renewable supply with a flexible, reliable backbone. Storage at this scale means grid operators can store excess solar or wind and release it when demand spikes, reducing outages and curbing the need for expensive peaking plants. It’s precisely the kind of backbone investors and policymakers have been looking for as India aims to double clean power capacity and accelerate the shift to a renewable-powered grid.

Why It Matters for India's Grid and Clean Power Push

So, what changes with Khavda in play? First, large storage like this acts as a demand-sharpening tool. It can shave the daily peak, smooth inter-hour fluctuations, and provide quick-response services to the grid. With a growing share of intermittent solar and wind, such batteries become a stabilizing force—making it easier to run more renewables without sacrificing reliability.

Second, the project aligns with India’s broader energy ambitions. Government targets call for expanding clean power capacity and deepening grid integration, with a clear tilt toward faster adoption of energy storage to support a higher renewable mix. A storage hub of this scale could also influence future auctions, pricing dynamics, and the business case for large-scale renewables paired with storage—helping buyers hedge risk and plan capacity more confidently.

Third, there’s a wider economic ripple. A project of this magnitude can spur domestic manufacturing, skilled jobs, and regional development in Gujarat. It also signals a growing appetite among Indian groups to deploy long-duration energy storage, which can unlock newer financial models and bring more players into the country’s evolving energy ecosystem.

The Path Ahead: Ambition, Risks, and What to Watch

Here’s the thing: the numbers are bold. 15 GWh by 2027 and 50 GWh within five years would make India a serious global player in grid-scale storage. Success will hinge on several practical factors. Financing needs to stay patient-friendly as the economics of storage mature. The supply chain for lithium-ion cells and modules must stay resilient amid global demand swings. Land, water, and permitting processes will need to be efficient, with strong safety and environmental safeguards. And the project must integrate smoothly with grid codes and market mechanisms so the storage doesn’t sit idle.

What to watch next? Policy nudges that bolster domestic battery manufacturing, streamlined approvals for big storage projects, and transparent pricing signals in electricity markets. If Khavda proves scalable and cost-effective, it could accelerate India’s transition to a renewable-heavy grid and push other developers to pursue ambitious storage deployments.
